I have handled quite a few of these non-resident selling cases before. You will need the help of a realtor, a lawyer and an accountant to finish the deal. The tax reporting portion is taking very long (around 4 months for stage one)because of the high volume of property transactions these days. The detail process is too complicated to post here. You can email me [email protected] or send me private msg - will probably need to explain to you over the phone.
